Shoe upper



FIG. 1 is a front perspective view of a shoe upper showing my new design;

FIG. 2 is a side view thereof; and,

FIG. 3 is a rear perspective view thereof.

The contrast in stipple shading between the two regions represents a contrast of appearance and no specific color, texture, or material is being claimed. The broken lines immediately adjacent to the shaded area represent unclaimed boundaries of the design. The unshaded eyelet region within the shaded area forms no part of the claimed design. The broken lines showing the remainder of the shoe are for environmental purposes only and form no part of the claimed design. 

CLAIM The ornamental design for a shoe upper, as shown and described.
